81615 divided by 26 
We want to figure out the number of times 81615 can be divided by 26.

Step 1:
8 divided by 26 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 26

Let's proceed to step 2:
The number 26 fits into 81 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 78 from 81 leaves us with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 26

Step 3:
26 goes into 36 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 26 from 36 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 26

Moving on to step 4:
101 divided by 26 is 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 313.0
If we subtract 78 from 101, we get 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 26

Step 5:
If we divide 235 by 26, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3139.0
If we subtract 234 from 235, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 6:
The number 26 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3139.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
When dividing 100 by 26, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 3139.03
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
When dividing 220 by 26, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 3139.038
Subtract 208 from 220 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
120 divided by 26 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 3139.0384
The remainder is 16 after subtracting 104 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
If we divide 160 by 26, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3139.03846
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
If we divide 40 by 26, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 3139.038461
Deduct 26 from 40 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
When dividing 140 by 26, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3139.0384615
If we take 130 away from 140, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3139.03846153
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 3139.03846153 and a remainder of 2.2e-08.
